RNF14FBD133R

Overview

The RNF14FBD133R is a fixed metal film resistor manufactured by Stackpole Electronics Inc. It features an axial through-hole package with a power rating of 0.25W (1/4W). The resistance value is 133 ohms with a tolerance of ±0.1%. The component operates within a temperature range of -55°C to +155°C and has a temperature coefficient of ±25ppm/°C. Physical dimensions are 0.093 inches in diameter by 0.250 inches in length (2.35mm x 6.35mm). It includes standard flame-retardant coating and complies with RoHS3 regulations.

Feature Summary

• Precision metal film construction for superior electrical stability
• Standard flame-retardant safety coating
• RoHS3 compliant and lead-free composition

Applications

• Precision analog signal conditioning circuits
• High-stability measurement instrumentation
• Medical device electronics requiring tight tolerances

Procurement Notes

Verify the specific suffix 'B' indicates the 0.1% tolerance variant when sourcing, as general series listings may default to wider tolerances. Confirm the axial lead configuration matches the target PCB footprint requirements. Ensure compliance with project-specific environmental standards such as REACH or California Prop 65 if applicable to the deployment region.

Selection Notes

Select this component when circuit design demands high precision (0.1%) combined with robust thermal performance up to 155°C. The low temperature coefficient ensures minimal drift under varying thermal conditions. Consider the axial form factor for manual assembly or through-hole manufacturing processes where surface mount alternatives are unsuitable.

Part Context

This part belongs to the RNF series of general-purpose metal film resistors from Stackpole Electronics. The series offers various tolerance options ranging from 1% to 0.1%, with the 'B' suffix denoting the highest precision tier. It serves as a reliable alternative to older carbon composition types, providing better noise characteristics and long-term stability for critical electronic applications.
